' To all whom it may concern:

Be it known that I, ROMAIN' DE BER- sAQUEs, a citizen of the United States, residing at llVashington, in the District of Columbia, have invented certain new and useful Improvements in Aeroplanes; and I do be hereinafter fully described and .then spe-4 Y citically defined in the appended claims.

I illustrate my invention in the accompanying drawings, in which Figure l is a top plan view of the apparatus. Fig. 2 is a side elevation of the in-I vention. Fig. 3 is a sectional View on line 3 3 of Fig. l. Fig. 4 is a detail perspective View' of a portion of the invention; Fig. 5 is a detail perspective view showing one of the propellcrs. Fig. G is a detail perspective view of the rear rudders, and Fig.`

7 is a detail sectional view showing the manner of connecting sections of the frame.4

Reference now being had to the details of the drawings by letter, A designates the body portion of the car, made preferably in the shape of a boat and provided with wheels B, affording means whereby the device may be supported on the ground and to assist in making an ascension without thc use of any auxiliary start-ing apparatus other than the motor of lthe craft. T he frame of the machine is made up of sections C which may be tubular or solid as may be.

desired and of any suitable material. The ends of the sections are fastened together by the couplings C and securely braced by means of the wires D. Mounted within the car or boat are two motors designated respectively by letters E and and fixed to the shafts of the engine are the two sprocket wheels E2. Journaled in suitable bearings in the frame are the horizontally disposed shafts F and Fand said shafts F have the sprocket wheels F2 keycdtliereto and about which and the sprocket wheels E2 .the sprocket chains l"4 pass. Similar sprocket wheelsl F5 are lined to the shaft F and sprocket chains FG pass about sprocket wheels F5 and the sprocket wheel E2 lupon the shaft of the motor E. Propellers (t are fastened to` the forward ends of the shnftF and similar propellers G', reversely arranged with reference to the propel'lers G,

4 are fixed to the shafts F.

Pivotally mountedupon the ears .'.I which project from the rod Il*f is a horizontally disposed-'wing 1 tapering to a poi-,it l and adapted tohave a swinging movement up and down for the purpose of guiding the craft 'as said wings impinge against theat-V inosphere while being driven forward. t similar wing, designated by letter J, is

` pivotally mounted upontlie ears J f fastened..

to'the lower porton of the frame and said wing J is positioned underneatllthe wing li and parallel thereto. A rod J* connects the pointed ends of each of said wings l and J. causing the same to move in tnison. Fastened to the oars K no'ectino from a crosspiece at the rear upper end otl the frame are the rear horizontally disposed wings K' connected by a rod K. Arms l project from Athe lower of the horizontally disposed wings at the rear of the apparatus and similar arms J 3 fronr the lower of the forward horizontal planes and rods N are fastened lat their rear ends to the eyes formed i in the ends of tho arms'li'.3 and their forward ends are iivotally connected to an operating lever which is piotcd upon a suitable support upon the car in' boat. O' is a curved segment ha ving tcetltengaged by the pawl Oz which is mounted uii'on the lever O and adapted to hold the latter in an adjusted position. Rods, designated by letters l), are pivoted at their rear endsl Lo the lever` O and their forward ends to the aims J3.. forming means whereby, as said-lever '..s moved in one direction or the other', the .wo

sets of horizontally disposed wings 'iii/ity bei' 100 moved in unison therewith.

A vertically disposed rudder F is pivotally mounted in bearings R" and suitable bracerods R2 are fastened to the outer free whereby, as the pulley R8 is rotated in one de afn direction or the other, the rudder R may he swung-to one side or the other.

Horizontally disposed Wings S are pivotally mounted at S upon pivots S2 and rods S3 connect the upper series oil` wings with a similar set of Wings S5 which are pivotally connected at S". Rods S" are pivotally 'connected to the outer ends of the lowerof said' wings S and their inner ends are fastened to the arms S8 projecting fro1nthe inner hinged end or' each Wing S5 and a rod T connects each arm S with a pivotal operat-A ing lever 'll' which is pivotally mounted upon the car, said 'lever T having aspring'- actuated paujl T2 adapted to engage a seg` nient bar to' hold the leverin an adjusted' posit-ion.

Hinged1 to thc top and alon portion of the lran'ieis'a'lin W are fastened at their inner ends to the :tree swinging edge of the iin and their outer edge to the frame, thusv allowing said fin to yield in opposite directions.- A simi-larin, designated by letter Y, is pirotedfto the bottom of the frame and has springs {Y secured at their inner ends to the edge of the fin and theirl outer edge to the frame and serving to coperate with the .Finsupon the top, to guide the craft as 'it moves through the air and prevent drifting sidey Wise. A suitable covering' of canvas or other material, designated hy letter X, is provided for the upper and lower portion oi' thetrame, forming the two aeroplanes and said Wings are also covered with any suitable material, such as eriva.

In operation', it will henoted thateach set ofpropellcrs, arranged in pairs,tWo at the front and two at the rear, are dri'venhy independent motors, the forward set o t propellers hai/'inor blades whichA rotate to'exert a pulling cl'ect by iinpingeinent of the blades against the atmosphere, While the blades of the rear set aredisposed to push and propel the apparatus. The twosets of' horizontally disposed planes in front and rear which are connected together bythe mechanism shown are adapted todae movedl hy the lever O in unison one' with another for t e purpose of raiding the craft up 'and flown i e, the ru ir R; Which is operated by means of the pulley R;@`,Iis adapteglto guide the craft latere While the Wings, d hy letters 'rid S5, are also Revelli) aus. down through the the enti-ai' and springs afloat in the event of its coming down' 1u' water and, by the provision of Wheels upon the boat, means is afforded for'alloWing-the craft. to move along the surface of the ground While acquiring sullicient momentum' to ascend. l

What I Yclaim to be new is l. An aeroplane comprising aboat, motors therein, Wheels upon ,'Wliich. said Vbloat is' mounted, a frame, propeller shafts journaled in suit-able bearings in said frame and pro pellers rotating with said' shafts, sprocket wheel and chain connections between the engine and propeller shafts, horizontally disposed Wings pivoted to thel front and rear.

4endsojt the frame, lever mechanism for rais-' ing 'and lowering 4said .wings in unison, 8. -vertically disposedrudder, means for operating the same, and yielding fins projecting from thetop and bottoni of the frame.

2.
